This paper presents a method for fitting 4-connected digital circles to a given set of points in 2D images in the presence of noise by maximizing the number of inliers, namely the optimal consensus set, while fixing the thickness. Our approach has aO(n3logn) time complexity andO(n) space complexity,nbeing the number of points, which is lower than previous known methods while still guaranteeing optimal solution(s).
